Channels from 101 to 119 are preferred, as they are legal to use and have relatively low traffic. The software driver sets the radio channel to channel 112 by default.

When the data rate is set to 2 Mbps, the radio uses two adjacent channels, so if students are using different channels to avoid interference they should be different by more than 2 MHz (e.g. 108, 110, 112, etc.).
